TAN K-HEATER AND FEED-COOKER.

Specification of Letters Patent.

Patented Dec. 26, 1905.

Application filed June 19, 1905. Serial No. 265,958.

To all whom, it may concern:

Be it known that I, WILLIAM-S. GRIFFITHS, a citizen of the UnitedStates, residing atRoscoe, in the county of Winnebago and State ofIllinois, have invented certain new and useful Improvements inTank-Heaters and Feed- Cookers, of which the following is aspecification.

The object of this invention is to construct a combined tank-heater andfeed-cooker.

In the accompanying drawings, Figure 1 is a plan view of my improvedtank-heater and feed-cooker located in 'a tank. Fig. 2 is a lengthwisevertical section on dotted line a a,

Fig. 1. Fig. 3 is a horizontal section through the heater above thegrate on dotted line b, Fig. 2.

The tank 1 may be of any construction and made of any suitable material.

My improved tank-heater and boiler is made of sheet material in order tobe of light weight, but may be made of cast material, if desired. Fromthe bottom 2 extend the two sides 3 and two ends 4, The top is open withthe exception of a space covered by the plate 5, which has two cut-awayportions. Two slides 6 and 7 are arranged to close or partially closethe cut away portions. Each slide has a lengthwise slot 8, through'whicha guiding-rivet extends.

A grate is located some distance above the bottom 2 of the heater andrests on the supports 9. This grate is in three sections 10, 11, and 12in order that they may be taken out through the top of the heater, sothat the ashes may be removed.

In two corners of the heater are formed vertical air passage-ways 13 and14, which communicate at their upper ends with the cut-away portion ofthe plate 5, and their lower ends communicate with the space beneath thegrate.

A smoke-pipe 15 communicates with the interior of the heater and has aconnection with the upper portion of the end 4. A damper 16 is locatedin the smoke-pipe.

A boiler is composed of the bottom 17, sides 18, and tapering top 19, tothe apex of which is connected a tube 20. A section of flexible tubing21 has a connection with the tube 20. An opening 22 is formed in the topof the boiler and is closed by the plug 23. The sides 18 of the boilerare enlarged above the top of the heater and form an oflset 24, whichrests upon the top of the heater.

The plate 5 is removable in order that fuel may be placed on the grate.After the fire is started air is admitted below the grate through thevertical air passage-ways 13 and 14, and the quantity of air admitted isregulated by the slides 6 and 7. This draft is regulated by the damper16, located in the smokepipe 15.

The same fire that is used to heat the water in the tank 1 will heat thewater in the boiler to a boiling-point, and the tubing 21 being insertedin the vessel containing the feed the feed will be cooked. By thisarrangement I can heat water in the tank and cook feed at the same time,and when I am not cooking feed the end of the tubing can be turned intothe water in the tank and assist the heater in heating the water.

When the heater is submerged in the water in the tank, access can be hadto the fire by removing the plate 5 without disturbing the boiler.

I claim as my invention In a combined tank-heater and feed-cooker, thecombination of the heater proper closed except at or near its top havingan open upper end, a removable plate closing a portion of the opening, agrate supported above the bottom of the heater, air passage-ways leadingfrom the top of the heater to the space below the grate, a smoke-pipecommunicating with the upper portion of the heater, a boiler supportedby the upper portion of the heater, and a flexible tube connected withthe upper portion of the boiler, said removable plate being situated atone side of the boiler.
